Which outcome occurs when coolant flow stagnates within a nuclear reactor core?

💡 Explanation

Fuel elements overheat because thermal energy can no longer be removed through convective heat transfer. At these temperatures, a phase transition, such as melting, can occur. Therefore the fuel phase transition occurs, rather than stable moderation/reactivity, which require active cooling.
